I would never have guessed it! I first checked the connection on the
receiver (inside the house obviously!) and just while I was unscrewing
it, the picture came back! For some reasons, the connection would break
if I screw the cable too tight!

I work in audiovisual and stage show sound, lighting and video
projection so I regularly have to troubleshoot such bugs in complex
systems. The connector inside the house would have been my last guess
since it's protected from the elements and not accessible to people and
pets to un-set it.

Besides, I measured 19 volts DC on the antenna connector.

Thanks all for the suggestions!
